is a toothed wheel or flange 29 which is adapted to interlock with complementary turn with said shaft by means of a suitable On the upper end of. the sleeve 28 28 is interlocked with the gear cl, the shaft 23 is driven by the smaller gear d at a lower rate of speed as compared with the speed of the crank disks. The sleeve'28 may be adjusted into engagement witheither of the gears c, d, by any suitable means. As shown a collar 30 on the lower end of the sleeve is. provided with trunnions 31 which areengaged by arms 32 fixed on a rock shaft 33. On the outer'end of the shaft 33 is an arm or lever 34 by means of which the shaft is rocked and the sleeve 28 is shifted up or down. The end ofrthe arm 34 is provided with a spring latch 35 which is adapted to engage eitherone of two openings 36 -to hold the sleeve in either its upper or lower position. It will be seen'that the speed of the driving mechanism can be in stantly changed simply by shifting the latch 35 from one opening 36 to the other.

It will be seen that the gears are incased and protected from the weather, dust, etc., by means of the crank wheels which are solid disks and the bracket 25. This bracket has'two flanges 37, contiguous to the crank disks and the crank disks are provided with overlapping flanges 38. The flanges 37 are preferably provided with grooves or gutters 39 in their outer'faces, as shown in Fig. 3, to carry off rain or other water and prevent its entrance into the gear case- The bracket 25 which carries the crank disks is adjustable about the axis of the shaft 23 and may be secured in any desired adjustment. As shown this adjustment is effected by pro viding slots in the upper plate of the stand ard 26, as shown in Fig. 4. Bolts 41' extend downwardly through the bracket 25 'and'the slots and rigidlyconnec't the bracket with its standard, the bolts being movable in'the' slots to adjust the angle of the hand-wheels with respect to the gun. One of the handles,

presumably the righthand handle 6, is pro v1ded with a simple and effective form of electric firing mechanism as follows Referring to F igs. 9 to 12, 42 indicates the a block of insulating material 45 which receives the terminals 46,47, of conducting wlresextending to the means for exploding the charge in the gun. These wirespreferably hang loosely from the handle and are joined into a single cable 48, as shown in Fig. 3, being, of course, insulated from each otherin said cable. The wires may be connected to the terminal posts or contacts 46, 47, in any suitable manner. The casing 44 is'closed on its top and "sides, opening only at the bottom, and the terminals are therefore thoroughly protected. Connected with the terminal 47 is a spring plate 49, the free end of which stands normally in proximity to the terminal 46, but o'ut of contact therewith. Conveme'nt means are provided for bringing theplate 49 into contact with the terminal 46' as follows: A vertical trigger shaft 50 has its upper end mounted 1n a bracket 51 extending inward from a guard plate or band 52 and itslower end extending through a bearing'53 in the upper plate of the 'box or casing 44; Upon the upper end of the shaft 51 is fixed an arm or trigger 54 which is conveniently situated to be engaged bythe forefinger of the hand which grasps the handle 72. Upon the lower end of shaft 50 is an arm 55 which is adapted to engage the spring plate 49 and press it'against the terminal 46 when the shaft 50 is rocked. thus electrically connecting the terminals 46, 47, and effecting the firing of the gun in a well known manner. To prevent leakage of the current apiece of insulating material 56 is placed between the arm 55 and the spring plate 49, being connected to one or other of said parts.

It will be evident that various modifications or changes. of the foregoing apparatus may be made without departing from the spirit or scope of the invention. Thus in Figs. 7 and 8 we have illustrated a modification in which the crank shaft 27 is mounted in the upper part of a standard 57 whichis adjustably carried by the base or carriage 22 of the gun, being connectedthereto by bolts 58 passing through slots .59. This standard 57 is broadly the equivalent of the standard 26 and the bracket 25. It will also be evident that various forms of changespeed gears may be substituted for those illustrated anddescribed and that the mechanical details of the firing handle may also be modified in various ways without departing from the invention, and furthermore that speeds are not limited to two, butmight be ,three or. even more, depending on the number of gears that areused;
